The existing chinese invention patent CN105188101B discloses a network switching scheme, which includes: acquiring the signal strength of a first network; judging whether the signal intensity of the first network is smaller than a first preset threshold value or not; if the signal intensity of the first network is smaller than a first preset threshold value, determining a second network; judging whether the uplink rate and/or the downlink rate of the first network is smaller than a corresponding second preset threshold value or not; if the uplink rate and/or the downlink rate of the first network is smaller than the corresponding second preset threshold, the uplink rate and/or the downlink rate of the second network are/is correspondingly obtained; judging whether the uplink rate and/or the downlink rate of the second network are correspondingly greater than the uplink rate and/or the downlink rate of the first network; and if the uplink rate and/or the downlink rate of the second network are/is correspondingly greater than the uplink rate and/or the downlink rate of the first network, switching from the first network to the second network in a state of keeping the connection network.
However, in the process of implementing the invention, the inventor finds that the prior art has at least the following problems:
1. the existing scheme only aims at the mobile terminal to switch between a wireless network and a mobile network, but for the intelligent commercial terminal in a commercial scene, a wired network is commonly used as a main connecting means, and a public place WIFI and the mobile network are used as standby connecting means, so that the existing scheme is difficult to solve the scene of wired network switching;
2. the existing scheme adopts a serial network evaluation scheme, namely, the signal intensity of a first network is judged firstly, the uplink rate and/or the downlink rate of the first network is judged when the signal intensity of the first network meets the condition, and the uplink rate and/or the downlink rate of a second network is judged when the uplink rate and/or the downlink rate of the first network meets the condition, so that the network switching speed is influenced;
3. the existing scheme can cause the user to pay extra cost when the speed measurement is carried out under a mobile network.
An embodiment of the present invention provides a network switching method, which is applied to an intelligent business terminal in multiple networks, and as shown in fig. 1, the method specifically includes the following steps:
and step S11, determining the current connection network and the connectable network of the intelligent business terminal.
In step S12, the connection capabilities of the current connection network and the connectable network are respectively scored.
In this step, the network types of the current connection network and the connectable network include at least one of a wired network, a wireless network, or a mobile network, and connection capabilities of the current connection network and the connectable network of the intelligent business terminal are periodically scored, respectively, when the current connection network and the connectable network are connected at the corresponding network types.
A wired network is a computer network that is connected using coaxial cable, twisted pair, and fiber optics. Factors affecting the connection capability of the wired network mainly include the current network speed, delay, packet loss rate and the like. In this embodiment, a PING instruction is sent through an ICMP (internet control Message Protocol) to obtain a network delay TTL; obtaining a packet loss ratio LOST according to the number of the sending packets and the number of the receiving packets; the network rate NS is calculated by downloading data from a server. In the embodiment of the present invention, normalization processing is performed in the calculation process for the final scoring comparison. Specifically, values of the combined network speed, the network delay time and the packet loss rate are obtained according to the pre-assigned weights of the network speed NS, the network delay TTL and the packet loss rate LOST, and then the values are assigned to the range of 0-100 through normalization.
In the embodiment of the present invention, the calculation formula of the connection capability score of the wired network is as follows:
(sin(NS×π/200)×0.7+0.2×LOST+sin(0.09×TTL×π/180)×0.1) ×100。
wireless network refers to a network for transmitting data over the air. Factors influencing the wireless network connection capability mainly include the current network speed, signal strength, delay, packet loss rate and the like. Similar to a wired network, a PING instruction is sent through an ICMP protocol to obtain network delay TTL; obtaining a packet loss ratio LOST according to the number of the sending packets and the number of the receiving packets; and calculating the network speed NS according to the server download data. In addition, the signal strength RSV of the wireless network is acquired from the WIFI module through the API. The method comprises the steps of obtaining values of combined network speed, network delay, packet loss rate and signal strength according to network speed NS, network delay TTL, packet loss rate LOST and weight values pre-distributed by signal strength RSV, and distributing the values to the range of 0-100 through normalization. In the embodiment of the present invention, a calculation formula of the wireless network connection capability score is as follows:
(sin (NS × π/200). times.0.6 + RSV/1000+0.2 × LOST + sin (0.09 × TTL × π/180). times.0.1). times.100. Mobile network refers to a way to connect to a network using a mobile device to enable internet access. Factors affecting the mobile network connectivity mainly include network connectivity, signal strength, etc. Similar to the wired network and the wireless network, the PING instruction is sent through the ICMP to obtain the network connectivity TTL, and the signal strength RSV of the wireless network is obtained from the WIFI module through the API, wherein the number of bytes of the PING instruction sent by obtaining the network connectivity in the mobile network is less than that of the PING instruction sent by obtaining the network delay in the wired network and the wireless network. And obtaining values of the network connectivity and the signal strength according to weights pre-distributed by the network connectivity TTL and the signal strength RSV, and distributing the values to the range of 0-100 through normalization.
In the embodiment of the invention, the method for calculating the connection capability score of the mobile network comprises the following steps:
(sin(0.09×TTL×π/180)×0.7+ RSV×3/1000)。
it should be noted that although the connection capability of the wired network, the wireless network or the mobile network involves different parameters, the connection capability of different networks can be reflected by the score values through the three formulas, and the score values are normalized in the three formulas so that the score values are compared at the same latitude. Preferably, in this embodiment, the score of the connection capability of the wired network, the wireless network or the mobile network is normalized to 0-100, so that the connection capability of different networks can be simply and clearly determined.
And step S13, when the connection capability score of the current connection network is higher than the first threshold, if the connection capability score of the connectable network is higher than the connection capability score of the current connection network and exceeds the second threshold, the connectable network is taken as a candidate network.
In this step, a first threshold of the connection capability score of the network is preset, and a second threshold of the difference of the connection capability scores of different networks is preset.
And when the connection capability score of the current connection network is higher than a first threshold value, the communication connection between the intelligent business terminal and the current connection network is stable. If the other connectable networks have a higher connection capability score than the currently connected network, the handover is not performed temporarily. And further judging whether the difference value between the connection capability score of other connectable networks and the connection capability score of the current connected network is higher than a second threshold value, and if so, taking the connectable network as a candidate network.
For example, assume that the first threshold is 40 and the second threshold is 30. The current wired network has a connectivity rating of 50, above a first threshold of 40; if the connection capability score of the wireless network is 70 at the moment, the difference between the score of the wireless network and the score of the current wired network is 20 and is lower than the second threshold value 30, no processing is carried out at the moment, namely the wired network cannot be switched, and the wireless network cannot be selected as a candidate network; if the wireless network has a connection capability score of 90, the difference between the wireless network score and the current wired network score is 40, which is higher than the second threshold value of 30, so that the wireless network is considered as a candidate network although the wired network is not switched.
As shown in fig. 2, after calculating the scores of the wired network, the wireless network, and the mobile network, the step specifically includes:
s21, determining the network with the highest score;
s22, judging whether the network with the highest score is the current connection network; if yes, no operation is required, if no, go to S23;
s23, judging whether the highest score is higher than the score of the current connected network by a second threshold value, if so, entering S24, and if not, needing no operation;
and S24, taking the highest-grade network as a candidate network so as to switch the network when the conditions are met.
And step S14, when the connection capability score of the current network is lower than or equal to a first threshold value, switching the candidate network into the current connection network of the intelligent business terminal.
In this step, when the connection capability score of the currently connected network is lower than or equal to the first threshold, which indicates that the communication connection between the intelligent business terminal and the currently connected network is unstable, the candidate network is switched to the currently connected network of the intelligent business terminal.
